Objective: To investigate the advantages of Color Doppler flow imaging (CDFI) in the diagnosis of complex vitreoretinal diseases.
Methods: Both CDFI and B-mode ultrasonographic studies were performed on 518 cases (678 eyes) vitreoretinal diseases, such as vitreous hemorrhage, posterior vitreous detachment, vitreoschisis, retinal detachment; choroidal detachment and diabetic vitreoretinopathy. The accuracy of diagnosis by B-mode and CDFI on the same case was compared with results of surgery.
Results: Comparing between CDFI and B-mode ultrasonographic, CDFI has more advantage in the diagnosis of the complicated vitreous-retina disease than other simple retina diseases (P < 0.05).
Conclusions: CDFI is good diagnostic method for complicated vitreoretinal diseases. Using CDFI sensitivity and veracity were obvious improved than using B-mode. CDFI can get more information for clinical diagnosis.
